Developer Respawn has confirmed that the broadly expected sequel its debut shooter, too. The original launched as an Xbox console exclusive.

Zampella, who is credited with helping shape the Modern Warfare series when he headed up Infinity ward, appeared to be unsure about whether the sequel will introduce a more robust single-player campaign.

"I wouldn't have done it differently," Zampella said reflecting on original's multiplayer-only approach.

"We set out to do it and it was one of our goals. I mean it obviously prohibits a certain group of people playing the game, and as content creators you want to get into as many people's hands as possible. We put some single-player elements in there though, and tried to mix it up. Maybe we could have mixed things up a bit better because some people blew right by it and didn't even see it because there was so much action happening around it. It's tough, because if you hit people over the head with it, it becomes intrusive, and there are people who don't want or care about it. Where does the needle fall? I think it takes a while to figure that out and we haven't figured it out yet."

"I think that's a fantastic way to do it," he said. "I think having the maps like that in packs, it does split the community and it makes it harder for matchmaking, it's messy. Yeah. I don't know we won't do it again, I can't say that for sure, but the idea would be to do something different."
